The four basic parts of a tapered roller bearing are:
- Inner Ring: The inner ring, also known as the cone, is the inner component of the bearing that contains the tapered raceway for the rollers. It is mounted onto the rotating shaft and provides the inner raceway for the rollers to move along.
- Outer Ring: The outer ring, also known as the cup, is the outer component of the bearing that contains the tapered raceway for the rollers. It is typically mounted into a housing and provides the outer raceway for the rollers to move along.
- Rollers: Tapered roller bearings contain tapered rollers that are arranged in a specific pattern between the inner and outer rings. These rollers are designed to support radial and axial loads and transmit forces between the inner and outer rings.
- Cage: The cage, also known as the retainer, is a component that holds the rollers in place and maintains their relative positions. It prevents the rollers from contacting each other and ensures proper distribution of the load between the rollers.
These four basic parts work together to enable the tapered roller bearing to support radial and axial loads, provide precise motion control, and withstand the demands of various applications.
